Abstract: The optimum control conditions for a plurality of looms are simply estimated with use of a trial loom. Hereby, the plurality of the looms are operated under a centralized control method. The looms, even if they vary in their peculiar characteristics, can be effectively operated by correcting standard control data for controlling the looms in response to variations of the loom characteristics. The present contralized control method can save much labor and time to improve productivity of the looms, by properly eliminating elaborate trial weaving processes.

Abstract: At the transmitting end, a pulse expansion is carried out digitally at the intermediate-frequency carrier level, the samples of the modulated carrier frequency being stored in a read-only memory (14) and the intermediate-frequency signal being generated directly by a digital/analog converter (15) without frequency conversion. At the receiving end, the received signal transformed via a single analog/digital converter (31) is digitally pulse-compressed at the intermediate-frequency carrier level by means of a real correlator (32) and then, after digital mixing in two digital mixing stages (34, 35), that is to say a so-called quadrature demodulation, evaluated in the form of I and Q channel signals. The invention can be used in pulsed radar systems with digital processing of all types. <IMAGE>

Abstract: The starting point in the production of a power semiconductor module is a ceramic baseplate (10) on which copper sheets and copper conductor tracks (2, 3, 20, 20', 22, 22') are mounted with the aid of a suitable method. The ceramic baseplate (10) is then scribed and broken. This produces ceramic side plates (11, 11', 12, 12') which are connected to the baseplate 10 via conductor tracks (20, 21, 22, 23). The side plates (11, 12, 11', 12') are then folded up, as a result of which the conductor tracks (22, 22') mounted on the side plates (11, 12, 11', 12') are moved into a plane above the base plane. As a result of suitable, possibly multiple breaking and folding of the side plates (11, 12, 11', 12') and suitable forming of the ends (25, 25') of the conductor tracks (22, 22'), direct connection can be made to the connection terminals of the power semiconductor chips (4, 4'). Electronic circuits (30) can be provided on the side plates (11, 11'). <IMAGE>

Abstract: The nitrification activity in a waste water stream or tank is expediently monitored by means of a waste water part-stream which is fed at a defined pH and specified residence time through a flow cell formed as a bioreactor which has a population of nitrifying microorganisms or receives them together with the waste water. The amount of pH correction medium is measured which is necessary to compensate the pH change associated with the nitrification. In addition, the turbidity in the flow cell can be measured. Depending on the objective, using an NH4<+> standard solution, the nitrification activity to be determined of a bacterial population to be evaluated can be determined or the ammonium load can be determined by means of a population of known activity, or else adaptation factors can be determined which are required for existing waste water loading and sewage sludge activities. The process can be used, in particular, for the regulation of feed to a nitrification reactor. The flow cells formed as miniaturised bioreactors can be offered in a standardised form having immobilised biomass, measuring probes and metering feed for test solution and pH-controlled pH correction medium feed having an electronic analysis and control unit. <IMAGE>

Abstract: A circuit for scanning a keyboard (1) is described which circuit is constructed as a matrix in the form of rows and columns and in which the rows are successively activated by means of a signal which, when the key (T) is pressed causes a signal at the associated column and in which for each actuation of a row, all columns are successively scanned. In this arrangement, the output (L40) of a counter (40) which cyclically counts up to a particular count, is converted in a demultiplexer (30) in such a manner that successively in time a particular number (m + n) of signals are generated at the rate of the counter for scanning rows of the matrix. A part (m) of these signals is always used for activating an identical number of rows of the matrix (L30,L10). Of the other signals generated in the demultiplexer (30), a selectably arbitrary number (1,2, ...(n-1)) can also be used for activating rows of the matrix (L31,L20) via correspondingly adjustable sections (201,202, ..., 208) of a multiplexer (20). Via the remaining sections of the multiplexer (20), which are not switched for actuating rows of the matrix, the columns of the matrix are switched through (L20,L21) to a further multiplexer (50) which, also controlled by signals at the output (L41) of the counter (40), successively scans the through-connected columns of the matrix at the rate of the counter (40) whilst a scanning signal is present at a row. <IMAGE>

Abstract: A colour electrophotographic apparatus includes a plurality of image forming units (25) each including a photoreceptor (27) and a corona charger (28), and using toner (31). In the apparatus, the image forming units (25) are arranged to be displaceable, with respect to an exposure position of an exposure device (24) and a transfer position of a transfer paper holding member (38) being fixed. During image formation, the image forming units (25) are moved to a predetermined position, and the obtained colour image is transferred onto paper sheet on the transfer paper holding member (38). Each of the image forming units (25) has a first image forming position confronting the transfer paper holding member, and a second image forming position different from the first image forming position. In a colour electrophotographic method of the present invention, when the time of use of each photoreceptor (27) for each single colour image in a colour image forming process is represented by T, and the time for electrostatically resting each photoreceptor (27) until the next use of the photoreceptor (27) is denoted by  t , a step in the relation of T<t is repeated during the colour image formation. By this electrophotographic arrangement, a compact colour electrophotographic apparatus simple in construction may be obtained, with a high speed operation during a single colour image formation, and favourable nature for maintenance. Furthermore, by the apparatus of the present invention, stable images may be obtained even during continuous use, without fatigue of the photoreceptor and undesirable temperature rise.

A contact (26) having a mating end (74), a mounting end (84), and a body section (94) extending therebetween is disposed in the channel (46). The body section (94) between the mating end (74) and the mounting end (84) defines an axis. The body section (94) also defines opposed first and second major surfaces (96,98). A first protrusion (104) extends from one of the major surfaces (96,98) proximate the mating end (74) of the contact (26) and a second protrusion (106 or 108) extends from one of the major surfaces (96,98) at a location spaced from the mating end (74) farther than the first protrusion (104). In this manner the contact (26) is caused to resiliently bend forming an "S" bend which provides a slight interference fit at spaced locations along the length of the contact (26) to retain the contact (26) in the channel (46).

Abstract: An apparatus and method in a tablet computer for disambiguating a handwriting input stream generated by a stylus-based user interface. A tablet application program interface (TAPI) of the present invention receives stroke data generated by a stroke made by a user on a digitizing tablet. The TAPI inserts the stroke data into a database. If the stroke is an editing gesture, the TAPI routes the stroke to a gesture recognizer which identifies an editing dialog. The TAPI then executes the dialog to perform operations on the database. If the application program is expecting text input, the TAPI continues to receive stroke data until it detects a closure event. The TAPI then forms a stroke group entry in the database by grouping all non-gesture stroke data received since the last closure event. The TAPI routes the stroke group data to a character recognizer, which returns candidate characters. The TAPI inserts the candidate characters into the stroke group entry. The TAPI notifies the application program each time it updates the database.
